Book excerpt: "Alaska is known as the land of snow, ice, and long, cold winters. Temperatures can drop to 40 or more degrees below zero, and, when the wind blows, wind-chill factors can go to minus 100 degrees Fahrenheit. When it is that cold, people and their pets go inside and huddle around warm stoves. Alaska's wild animals don't have heated houses. Where do they go at 40 below?"--Back cover
